Abstract (en)

[origin: GB2246713A] Blood is filtered at more than 25 millilitres per minute to reduce the leucocyte content through a filter housing having a tangential inlet, an inward flow annular filter element 52 comprising a mass of polymeric fibres with a CWS7 over 52 dynes/ cm and an air vent 30 separated from the rest of the filter by a liquid-repelling porous membrane 31. Blood passes from the inlet to element 52 through a preliminary foam plastic filter element 50, which coalesces any air bubbles to facilitate separation. The filter is used in conjunction with an artificial lung, during open heart surgery. <IMAGE>
